COMBINE D TYPE-WRITING AND ADDING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 778,595, dated December 27, 1904.

Application filed May 2,1904. Serial No. 206.011.

To aZZ whom it may concern:

Be it known that I, EMIL N. MILLER, a citizen of the United States, residing at Orange,

county of Essex, State of New Jersey, have 5 invented certain new and useful Improvements in a Combined Type-Writing and Adding Machine, of which the following is a speci' devices'controlling the action of the accumu lating or adding mechanism will be prevented '1: until the said mechanism is in proper position to be actuated. I

With this object in view the invention consistsin the combination, with a laterally-mow able accumulating mechanism and an actuat- -ing device therefor, of means for locking said actuating device against movement when the accumulating mechanism is not in position to be actuated thereby. I

In the accompanying drawings, Figure 1 is 5 a vertical longitudinal sectional view through a combinedtype-writing and adding machine having the subject-matter of the presentinvention embodied therein. Fig. 2 is a perspective view of portions of the said machine. 3 Fig. 3 is a detail View.

Referring to the drawings, in the several figures of which like reference characters designate corresponding parts, 1 designates the frame of the machine.

The carriage 2, in which the paper roller or platen 3 is mounted, also supports the accumulating mechanism, which may be of any suitable character adapted to be actuated by a single member '-ordevice mounted in the 4 frame of the machine and past which the accumulating mechanism is moved laterally by the ordinary step-by-step feed of the carriage. As shown, said accumulating mechanism invcludcs a plurality of toothed wheels 4, one 45 for each numeral order, which are mounted in suitable bearings on a frame consisting of a series of parallel plates 5, and each of said wheels meshes with an indicator disk or pinion 6, bearing on their peripheries the digits 1 to 9 and 0. The frame of the accumuthe wheels 4 of said mechanism are'actuated.

Said sector is carried by a lever 9, suitably fulcrumed in the frame 1 of the machine and controlled in its movements by a plurality of selector or control keys 10. As shown, said keys 10 are each adapted to be operated in conjunction with a type-bar 11, which is provided with a suitable type for printing on the paper supported by the platen 3 the numeral corresponding to that indicated on the head of the key 10. It will be understood that the extent of movement imparted to the actuating-sector 8 by the different controller-keys 1O varies in such a manner that the amount of rotation of the wheel 4 of the accumulating mechanism due to the operation of either of said keys will be such as to cause the indicating-disk /6, connected with said wheel to bring into view the numeral corresponding to that on the key which is operated, or the sum of such numeral and the one previously displayed by said disk. The accumulating mechanism is of course provided with suitable devices for carrying from one numeral order to another or causing the disk 5 of each order to move one step on the completion of every revolution of the corresponding disk of the next lower order. It is not necessary, however, for the purposes of-disclosing the present invention to illustrate or describe in detail the construction or operation of such mechanism. As before stated, various forms of accumulating mechanisms may be employed, and therefore it will be understood that the present illustration is merely conventional.

As the controller-keys 10 are only intended for operating the accumulating mechanism, the machine is provided, in addition to said keys, with the letter, numeral, and character keys 11 and type commonly found in typewriting-machines, and it is very important that said keys 10 should not be operated .ex-

cept when one of the wheels 4 of the accumulating mechanism is in .position to be engag-ed by the sector 8. Therefore means are the carriage 2 brings the accumulating mechin its lower position as long anism into position to be operated by said sector, when said lock is automatically withdrawn. Said locking means includes a bar or strip 12, which extends transversely. across the machine adjacent to the stems of the keys 10, being supported by arms 13, which are mounted on a rock-shaft l4, journaledin suitable bearing s in the frame of the machine. To saidshaft is connected near its free end a slot 16, into which extends a pin at the upper end of a link 17, the lower end of which link is connected'to one arm of alever 18. The other arm of. said lever is connected to a lug or ear 19 on a bail 20, which is pivoted to opposite side walls of the frame 1 and normally held in an elevated position by springs 21. The bail 20 is provided at a suitable point with an upwardly-projecting tooth 22, which extendsinto the path of a trip bar or plate 23, connected to the frame of the accumulating mechanism on the carriage 2.

Normally the springs 21 hold the bail .20 in an elevated position and the shaft 14 in such position that the bar or strip 12, carried thereby, is swung forward and beneath projections 24:, one on the stem of each key 10, as shown in Fig. 2 of the drawings. The said keyswill thus be locked in their elevated positions and actuation of the sector 8 prevented until in the lateral movement of the carriage the bar or plate 23 contacts with the tooth 22 and depresses the bail 20, thus rocking the lock-bar 12 rearwardly out of the path of the projections 24 on the key-stems. The plate 28 extends throughout the width of the accumulating mechanism, and thus the bail 20 is held as any member of the accumulating mechanism is in position to be operated by the sector 8. 'hen the plate 23 is by the movement of the carriage 2 carried past latter under the action of the springs21 is returned to its upper position and the bar or strip 12 is again moved forward beneath the projections 24.

In order that accurate results may be at tained, it is important that whenever either of the controller-keys is operated all of the other similar keys shall be locked in their elevated positions until the full movement of the key first operated is completed. To accomplishthis result, the stem or bar of each key 10 is provided on its rear edge 'with a cam-surface 25, adapted to coact with a finger or dog 26 on the rock-shaft 14. When. the bail 20 is rocked, as above described, to withdraw the bar or strip-l2 from operative 'position, the

said fingers 26 are brought into position to be an arm '15, having the tooth 22 on the bail 20, the I engaged by the cams 25 on the stems of keys 10 whenever said keys are depressed. As either keylOis depressed itscam-surface 25 will contact with the adjacent finger 26 as the 1 pro ection 24.- passes below the bar 12, and thereby the shaft 14 will be rocked to swing said bar forward beneath the projections 24;

' the lever 15 permits of this movement without affecting the position of the bail. As the depressed key is raised by action of asuitable lifting-spring and the cam-surface 25 thereon passes above the finger 26 the bar or strip 12 is again swung rearwardly by the action of a spring 27, connecting the lower end of one of the supportingarms 13 of said bar witha stationary pin or stud on the machine-frame. A stop-pin 28 limits the rearward movement of the bar 12.

The accumulating mechanism can only be operated by the sector 8 when the carriage is 1n lower-case position. Therefore when the carriage or platen is shifted rearwardly to the upper-case position means are provided for positively locking the keys 10 even though the accumulating mechanism should at that time be opposite its actuating-sector. Such means are illustrated in Fig. 3, in which it will be seen that the stem 30 of the shiftkey by which the movements of the carriage or platen fromlower-case to upper-case position are controlled is provided with an arm 31, having at itsrear end a lateral projecting stud 32, which when said shift-key is depressed will contact with the forward end of lever 15 and through said lever rock the shaft 14 to move the bar or strip 12 into operative position. I

It will be understood that the carriage 2 is moved laterally of the machine by the usual escapement or step-by-step feed mechanism actuated by operation of either of thekeys of the machine. In thepresent case it is not deemed necessary to illustrate in detail either said carriage-feed mechanism or other parts of the type-writing mechanism not directly connected with this invention, as it is evident that the latter can be embodied with various forms of type-writers other than the one se lected for purpose of illustration.
